[Pharo-project] dumb problem inserting comments in pharo book
by Esteban Lorenzano March 19, 2011

March 19, 2011

Hi, I tried to add a comment at page NewInspector (asking for removal, since it has no sense). Mysteriously, the comment was saved at new page. So, I tried to "fix" the error adding a new comment, saying "I was talking about NewInspector"... and I really don't know where that comment was posted, I can't find it now :( I'm sorry for the mess... can you delete both comments for me??? (and the duplicated NewInspector page, too) Cheers, Esteban

Then you would just do: you have a MC package FOO it contains FOO-Cat1 --> One RPackage Foo you have a MC package FOO it contains FOO-Cat1 FOO-Dog2 --> One RPackage Foo. We loose the sub structure. For the sub-structure, the way categories are now used in PackageInfo packages is that they do not denote sub-packages, but just some convinient sorting without semantic (to the language) meaning, just as method categories. So the perfect thing would be to have some form of ordering inside of RPackage (e.g. tagging). The case "Now you create a new Category" would not exist, as there are no categories anymore. Categories should die. Marcus -- Marcus Denker -- http://www.marcusdenker.de INRIA Lille -- Nord Europe. Team RMoD.

[Pharo-project] Equality and hash made easy
by Noury Bouraqadi March 19, 2011

March 19, 2011

Hi, I proposed in early february an enhancement to avoid having redefine hash and = together and I would like to see it integrated in 1.3. My idea is that the implicit link between these two methods should be supported by the system. A first solution is proposed on the issue tracker http://code.google.com/p/pharo/issues/detail?id=3657 To make instances of some class comparable, simply make the class use the TEquality trait. TEquality relies on message valuesToCompareForEquality sent to objects for both = and hash. The default implmentation of this message is provided by Object. Override ONLY valuesToCompareForEquality method for custom equality check.

Re: [Pharo-project] Run a Pharo world on WebBrowser.

In the past, the way etoys was used was that you install the VM with a standard image as a plugin for the browser. Then .pr (Projects) where loaded just like much more interactive web pages. There where multiple problems with that a) It's a lot of work to keep the vm plugin working for real. A lot of time was invested from the side of the etoy team on that. b) Even though it's just "please install the plugin", people just don't do it. (partly because they are not allowed to, e.g. in a school setting) c) Projects... are problematic. Far too low level. Changes on the image lead to big problems if you want to be able to load old projects (as they are just a dumb of parts of the image... this will be especially fun as soon as you start to change real things in the system.) No idea what the latest state is.. but projects like Scratch decided it's easier to do a java (or flash?) based player app for the Scratch projects instead. There are two interesting developments: -> JavaScript. Millions are invested in JS VM technology. So one can start to do real smalltaks in JS. (Personally, I think having your own real VM, not one implemented ontop of another VM is preferable, though. Especially if you plan to do real strange things in the futuer as opposed to just wanting a smalltalk system in the browser.) -> Google Native Client. That one is very impressive. But it's unclear what googles plans are. We now they have no fear of promoting something and yet then kill it after people start to use it for real...

[Pharo-project] Run a Pharo world on WebBrowser.

March 19, 2011

I thinking do an application for run in desktop, browser and mobile devices. I want know if is REALLY possible run Pharo in a web browser, like a flash/java applet/silverlight application, without problems. Somebody has proved that? How is difficult for the user install the mechanism in browser for run the Pharo image?

[Pharo-project] [call for help] Bugtracker
by Marcus Denker March 18, 2011

March 18, 2011

There is a bug tracker at http://code.google.com/p/pharo/issues/list With currently 524 open bug reports. With 1.2Core now being released, it would help *a lot* if people who submitted a report would check that report in the loght of a released 1.2 and an actively developing 1.3... -> Has the bug already been fixed? Reports that are already fixed are just incredible wasteful. -> Does the submitted code need to be updated for 1.3? -> Did someone ask a question in the meantime? -> after a long discussion, wouldn't a sumary help to understand what the next action is? *A lot* of the reports could really need some love from the person who submitted it orginally. We should really think about some scheme to auto-close bug reports. E.g. if someone asks a question and the original submitter thinks that it's not even worth to anwer "I don't know", then a bug report should be closed after some generous amount of time (e.g. 6 Months), as it's definitly not important.
